Definition

Mitochondrial biogenesis refers to an increase in mitochondrial volume as well as possible changes in mitochondrial composition. In skeletal muscle, this is an adaptation that results from repeated bouts of exercise (Fig.  1a). Mitochondrial biogenesis in skeletal muscle promotes a shift toward a greater  oxidative capacity in the muscle fibers, leading to higher  muscle endurance.
